The Dolphins play their third and most important preseason game Saturday night so now is as good a time as any to take a look at the entire roster on a position by position basis.

I am not assuming anything on here as you will see. I think, given some of the moves of this new regime, that is a safe way to go. Let me know where you agree and where you disagree.

QB: In: Chad Henne, Chad Pennington. Onthebubble: Josh McCown and John Beck: Theskinny: Although Sparano has said the team might carry four guys, that is hard to fathom. More likely the team keeps three with McCown and Beck sweating out the cuts. The Dolphins are hoping some QB around the league goes down this weekend, making a trade involving McCown or Beck palatable.

RB: In: Ricky Williams and Ronnie Brown. Onthebubble: Patrick Cobbs, Jalen Parmele. Ontheouts?: Lex Hilliard. Theskinny: Despite the ESPN rumor that Brown might be gone from the team this season, it is hard to believe the Dolphins would simply push him out without getting value in return. And no one is giving up a first-round pick for Brown so there is no return value seemingly available. The coaching staff, particularly Sparano, likes Cobbs. But despite his effort and desire, his production (10 carries, 25 yards) has been pedestrian this preseason. Parmele runs a little high, but he runs hard. Hilliard has disappeared at times this training camp and can hope for a practice squad spot at best.

WR: IN:Ted Ginn Jr, Derek Hagan. On the bubble: Ernest Wilford, Greg Camarillo, Davone Bess, Anthony Armstrong. Ontheouts? Jayson Foster, David Kircus. Theskinny: The Dolphins probably keep five of these guys. They would listen to trade offers for Wilford with a return trip to Jacksonville a slight possibility. Absent that, a good game by Wilford on Saturday assures him of making the team. Camarillo and Bess have been fairly consistent but they need to excell on special teams to nail down a position. Armstrong has become Miami's most explosive receiver in practices the last week or so. Kircus, perhaps Miami's best deep threat in practices, had a good chance to make the team until Armstrong started flashing skills.

FB/TE: IN: Anthony Fasano, David Martin. Onthebubble: Reagan Mauia, Boomer Grigsby, Justin Peelle, Sean Ryan. Ontheouts? Matthew Mulligan. Theskinny: The Dolphins will probably keep five from this group and that normally breaks down to two FBs and three TEs, but because the Dolphins use TEs in the backfield as blockers, the team has flexibility on personnel. The decisions will boil down primarily to special teams. The better special teamers will get the nod and, based on past performances, that is an advantage for Grigsby and Peelle first, followed by Ryan and Mauia.

OL: In: Jake Long, Justin Smiley, Samson Satele, Donald Thomas, Vernon Carey, Trey Darilek. Onthebubble: Darren Heerspink, Matt Spanos, Irechuku Ndukwe. Ontheouts?: Mike Byrne, Shawn Murphy. Theskinny: Thomas is the most pleasant surprise of any rookie given his draft status (6th rounder). Long has played as advertised while Darilek is a Dallas Cowboys favorite of Sparano's and he also plays multiple positions. The Dolphins have very poor depth behind the starters so even those players making the roster should hold their breath until after Miami studies the talent available on the waiver wire. Murphy, promising in offseason camps, has not physically won a job on the roster although his draft status could still save him.

DL: In: Kendall Langford, Vonnie Holliday, Jason Ferguson, Matt Roth, Phillip Merling. Onthebubble: Randy Starks, Paul Soliai, Rodrique Wright. Ontheouts? Anthony Toribio, Lionel Dotson. Theskinny: The Dolphins are encouraged by their youngsters (Langford and Merling) and have to feel good about the maturity and professionalism Ferguson and Holliday bring. Beyond that, the depth is questionable. Starks has been slow to get comfortable in Miami's system and Soliai has been inconsistent as he tries to learn to be a professional. The cuts here should not be difficult.

LB: In: Channing Crowder, Akin Ayodele, Reggie Torbor. Onthebubble: Joey Porter, Charlie Anderson, Quentin Moses, Titus Brown, Edmond Miles, Rob Ninkovich. Ontheouts?: Kelly Poppinga, Maurice Fountain, Junior Glymph. Theyskinny: I know, I know, you think Porter is definitely on the team. That may be true based on reputation and his contract, which included a $20 million guarantee. But if you measure guys making the team based on production this preseason, Porter is a big question mark based on his inability to contribute because of injuries. The Dolphins may think this is the start of a troubling trend and may try to trade Porter. Anderson was starting early in training camp but injuries have kept him from earning a roster spot as well. He was back practicing this morning and may try to play Saturday to open the coaching staff's eyes. Brown is a darkhorse that coaches love for his desire, effort and potential. Moses needs to show more consistency.

DB: In: Andre' Goodman, Will Allen, Joey Thomas, Yeremiah Bell, Nathan Jones, Chris Crocker. Onthebubble: Jason Allen, Michael Lehan, Renaldo Hill, Keith Davis. Ontheouts? Will Billingsley, Courtney Bryan, Chris Roberson. Allen, Lehan and Hill are probably on the team so I don't want to hear any crap about where I put them. The fact is there are still questions among the coaching staff on all of those guys so one cannot simply anoint them to a roster spot or assume they have one locked up -- no matter what anybody says. Davis can make the team with a solid special teams performance Saturday evening. The guys on the outs were in the game last weekend when Jacksonville bombed the Miami secondary in the final quarter.

Spec: In: K Dan Carpenter, P Brandon Fields, and LS John Denney. Theskinny: It must be nice to be them.
